A Walt Disney World patron on a ride with her grandson found a loaded gun on her seat.

Officials said Wednesday that the woman found the automatic gun on the Dinosaur ride at Animal Kingdom. The woman gave the loaded gun to a park attendant who then contacted her manager and authorities.

The owner of the gun, Angelo Lista, told authorities he discovered his gun was missing several minutes after leaving the ride. He has a concealed weapons permit.

Lista told authorities he didn't know Disney World patrons weren't allowed to bring guns. He said he thought the security checkpoint at the entrance to the central Florida park was only so guards could check bags for bombs or explosives.

Disney World prohibits patrons from bringing weapons of any kind on its property.
